I think the language needs a good facility to support multi-line string literals in code, and the Python triple-quote syntax is the cleanest of all the ones I've used among various languages.</div><div><br></div><div>I would like to see some more detail/clarification in the proposal before I could give it a full +1 though:</div><div><br></div><div>1. The proposal shows that double quotes don't need to be escaped in these literals; similarly, string interpolation is supported with the usual \(...) syntax. How is escaping of other characters handled within these strings? Is it affected or not? If I include \n in my multi-line string, does that insert a newline at that location, or is it the literal "\n"? (I expect the former, but I'd like to see it spelled out.)</div><div><br></div><div>2. If I want to be terrible and include the literal """ in the content of my string, how would I escape that? Is \"\"\" sufficient/the only way/the right way? Does it make a difference if it's leading the line (with the exception of whitespace) or in the middle of a line?</div><div><br></div><div>3. Deciding how much leading whitespace to strip based on the indentation of the *closing* quotes seems a bit strange/magical to me, but I honestly can't think of a cleaner way to do it. This at least makes the amount of leading space something that I can explicitly control (and IDEs like Xcode could color in the margin accordingly to make it clear how much of the leading space is actually part of the string).</div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word" class="gmail_msg"><div class="gmail_msg"><div class="gmail_msg"></div><div class="gmail_msg"><span class="m_5262404792494791902Apple-tab-span gmail_msg" style="white-space:pre-wrap"> </span>• Is the problem being addressed significant enough to warrant a change to Swift?<br class="gmail_msg"></div></div></div></blockquote><div><br></div><div>Yes.
